Agreed. All we've really done so far is establish surface-based perturbations for when the low-level jet ramps up after sunset.Should note that this is not supposed to peak until around 00z or even after per most high res guidance. Think Conway might have some issues later if this cell keeps going into Central AR.
Is it possible more cells could fire in the S to NE OK vicinity as the LLJ increases in strength?Agreed. All we've really done so far is establish surface-based perturbations for when the low-level jet ramps up after sunset.
Imo the thing preventing it from taking off is meager low level shear, as seen from Ft Smith VWP and as mentioned in previous commentsThe cell just to the west near Lavaca is interacting with the main one, which could be holding it back from taking off, at least for the moment.
